Repeating commands						*repeating*

Chapter 26 of the user manual introduces repeating |usr_26.txt|.

                                      Type |gO| to see the table of contents.

==============================================================================
Single repeats						*single-repeat*

							*.*
.			Repeat last change, with count replaced with [count].
			Also repeat a yank command, when the 'y' flag is
			included in 'cpoptions'.  Does not repeat a
			command-line command.

							*@:*
@:			Repeat last command-line [count] times.

Simple changes can be repeated with the "." command.  Without a count, the
count of the last change is used.  If you enter a count, it will replace the
last one.  |v:count| and |v:count1| will be set.

If the last change included a specification of a numbered register, the
register number will be incremented.  See |redo-register| for an example how
to use this.

Repeating an insert |ins-repeat| re-executes the whole session, including
non-jump cursor-moves: "iab<Left>c<Esc>." produces "acb", not "c".  Note that
jumps (mouse, |i_<PageUp>|, …) split an insert session.

Repeating a Visual-mode command re-executes the captured keysequence,
selection included.  See |visual-repeat|.

							*motion-repeat*
Example: a "," mapping that repeats the last motion, like |;| but for any
motion ("3w", "fx", "/pat<CR>"): remember the last "motion" |CmdAtom| and
replay its keys: >lua
    local last ---@type string?
    vim.api.nvim_create_autocmd('CmdAtom', {
      pattern = 'motion',
      callback = function(ev)
        last = ev.data.keys
      end,
    })
    vim.keymap.set('n', ',', function()
      -- CmdAtom is deferred: schedule the replay after any pending event,
      -- so `last` is fresh when "," follows a motion.
      vim.schedule(function()
        if last then
          vim.api.nvim_feedkeys(last, 'n', false)  -- "n": already resolved
        end
      end)
    end)

Multiple repeats					*multi-repeat*

						*:g* *:global* *E148*
:[range]g[lobal]/{pattern}/[cmd]
			Execute the Ex command [cmd] (default ":p") on the
			lines within [range] where {pattern} matches.

:[range]g[lobal]!/{pattern}/[cmd]
			Execute the Ex command [cmd] (default ":p") on the
			lines within [range] where {pattern} does NOT match.

							*:v* *:vglobal*
:[range]v[global]/{pattern}/[cmd]
			Same as :g!.

Example: >
	:g/^Obsolete/d _
Using the underscore after `:d` avoids clobbering registers or the clipboard.
This also makes it faster.

Instead of the '/' which surrounds the {pattern}, you can use any other
single byte character, but not an alphabetic character, '\', '"', '|' or '!'.
This is useful if you want to include a '/' in the search pattern or
replacement string.

For the definition of a pattern, see |pattern|.

NOTE [cmd] may contain a range; see |collapse| and |edit-paragraph-join| for
examples.

The global commands work by first scanning through the [range] lines and
marking each line where a match occurs (for a multi-line pattern, only the
start of the match matters).
In a second scan the [cmd] is executed for each marked line, as if the cursor
was in that line.  For ":v" and ":g!" the command is executed for each not
marked line.  If a line is deleted its mark disappears.
The default for [range] is the whole buffer (1,$).  Use "CTRL-C" to interrupt
the command.  If an error message is given for a line, the command for that
line is aborted and the global command continues with the next marked or
unmarked line.
								*E147*
When the command is used recursively, it only works on one line.  Giving a
range is then not allowed.  This is useful to find all lines that match a
pattern and do not match another pattern: >
	:g/found/v/notfound/{cmd}
This first finds all lines containing "found", but only executes {cmd} when
there is no match for "notfound".

Any Ex command can be used, see |ex-cmd-index|.  To execute a Normal mode
command, you can use the `:normal` command: >
	:g/pat/normal {commands}
Make sure that {commands} ends with a whole command, otherwise Vim will wait
for you to type the rest of the command for each match.  The screen will not
have been updated, so you don't know what you are doing.  See |:normal|.

The undo/redo command will undo/redo the whole global command at once.
The previous context mark will only be set once (with "''" you go back to
where the cursor was before the global command).

The global command sets both the last used search pattern and the last used
substitute pattern (this is vi compatible).  This makes it easy to globally
replace a string: >
	:g/pat/s//PAT/g
This replaces all occurrences of "pat" with "PAT".  The same can be done with: >
	:%s/pat/PAT/g
Which is two characters shorter!

==============================================================================
Complex repeats						*complex-repeat*

							*q* *recording* *macro*
q{0-9a-zA-Z"}		Record typed characters into register {0-9a-zA-Z"}
			(uppercase to append).  The 'q' command is disabled
			while executing a register, and it doesn't work inside
			a mapping and |:normal|.

			Note: If the register being used for recording is also
			used for |y| and |p| the result is most likely not
			what is expected, because the put will paste the
			recorded macro and the yank will overwrite the
			recorded macro.

			Note: The recording happens while you type, replaying
			the register happens as if the keys come from a
			mapping.  This matters, for example, for undo, which
			only syncs when commands were typed.

q			Stops recording.
			Implementation note: The 'q' that stops recording is
			not stored in the register, unless it was the result
			of a mapping

							*@*
@{0-9a-z".=*+}		Execute the contents of register {0-9a-z".=*+} [count]
			times.  Note that register '%' (name of the current
			file) and '#' (name of the alternate file) cannot be
			used.
			The register is executed like a mapping, that means
			that the difference between 'wildchar' and 'wildcharm'
			applies, and undo might not be synced in the same way.
			For "@=" you are prompted to enter an expression.  The
			result of the expression is then executed.
			See also |@:|.

							*@@* *E748*
@@			Repeat the previous @{0-9a-z":*} [count] times.

							*v_@-default*
{Visual}@{0-9a-z".=*+}	In linewise Visual mode, execute the contents of the
{Visual}@@		register for each selected line.
			See |visual-repeat|, |default-mappings|.

							*Q*
Q			Repeat the last recorded register [count] times.
			See |reg_recorded()|.

							*v_Q-default*
{Visual}Q		In linewise Visual mode, repeat the last recorded
			register for each selected line.
			See |visual-repeat|, |default-mappings|.

							*v_Q*
{Visual}Q		Place a cursor on each line of the Visual selection.

							*:@*
:[addr]@{0-9a-z".=*+}	Execute the contents of register {0-9a-z".=*+} as an
			Ex command.  First set cursor at line [addr] (default
			is current line).  When the last line in the register
			does not have a <CR> it will be added automatically
			when the 'e' flag is present in 'cpoptions'.
			For ":@=" the last used expression is used.  The
			result of evaluating the expression is executed as an
			Ex command.
			Mappings are not recognized in these commands.
			When the |line-continuation| character (\) is present
			at the beginning of a line in a linewise register,
			then it is combined with the previous line.  This is
			useful for yanking and executing parts of a Vim
			script.

							*:@:*
:[addr]@:		Repeat last command-line.  First set cursor at line
			[addr] (default is current line).

:[addr]@						*:@@*
:[addr]@@		Repeat the previous :@{register}.  First set cursor at
			line [addr] (default is current line).
